A demon's offer

(Gonna try and tell this one from Doug's perspective.)

I couldn't bring myself to turn my head, all I could do was stare back in the mirror, I tried to turn my head but her immense tits pressed against the back of my head, she kept me looking forward into the mirror. I gulped, she licked her lips as I finally managed to find my voice. "W-what kind of deal?" The words had barely left my mouth, a big grin spreading across her face as she pressed against me further. Her body practically pinning me to the counter as her body bent forward, whispering to me. "Oh sweetie, did you not know what that spell would do? Oooh was it an accident~? Something you thought wouldn't work~? Mmm these are the rare occasions that demon's like me DREAM of darling~" As she spoke into my ear, practically moaning at the end I felt it. Her enormous futahood pressing against my ass, fuck it felt like it was still getting bigger!

"Mmm darling you summoned a VERY pent up demon... The deal is simple, you help me to UNLOAD ALL I've been saving up, and I grant you a wish. I won't even take a sliver of your soul darling, tell me... which do you prefer~? Human? Or are you more of a naughty boy~?" She grasped my body carefully, gently almost and lifted me up enough so I could see it. Her monstrous futa cock in it's glory, she was well over a foot long already, but seemed to just keep growing slowly. Suddenly I saw her cock glow pink for a few moments, when it faded her normal shaped cock was replaced with something far more CANINE in nature, a brighter red with a knot and tapered tip. Then her cock glowed once more, replaced this time by an impossibly THICK equine shape, a flare at the end. "Mmm your soul speaks to me boy, it tells me what you prefer... tell me your wish cutie, I'll grant it and give your soul the DEEP filling it desires~" As she finished speaking her cock glowed one last time, what was revealed when the glow faded I felt such fear at what I saw, I didn't even realize my ass twitched and tingled at the sight. The demon's enormous rod had a truly MASSIVE knot at the base, but every single inch was horse like up until the tip which seemed to be mostly human shape aside from a slight flare it had at the bottom of the crown.

"Mmm what's your wish darling~? Go ahead... make your wish~" She moaned into my ear once more, my body quivering as she held me up, that bestial cock throbbing as it hung between her legs and my own.
